The revised GRAP to come into force w.e.f. 01.10.2023 in the entire NCR
The Citizen Charter has also been amended to enable citizens to more actively contribute towards pollution control measures
Towards its continued commitment to ameliorate the overall air quality of the National Capital Region , the Commission for Air Quality Management in NCR & Adjoining Areas  has taken significant efforts to abate air pollution and strategically address the air pollution related challenges across different sectors in the region. Moving ahead with this vision and to further strengthen the measures to combat air pollution especially ‘Severe’ and ‘Severe+’ air quality stages generally encountered in NCR during peak winters, the Commission today announced revision in the existing Graded Response Action Plan .

Following a differentiated approach, GRAP for NCR was formulated after careful consideration of scientific data, stakeholder inputs and expert recommendations and GRAP has now been revised based on the experience and learning of last year.
